About this gig

I'm a Senior Full Stack Java Engineer building production systems for fintech and banking clients, including a direct engagement with UK's stock market.

Backend:

  • Spring Boot, Spring Security, Spring AI
  • REST and GraphQL API design (including N+1 query optimization / BatchMapping)
  • PostgreSQL, MongoDB schema design, indexing, migrations
  • Kafka, Redis for event-driven and caching architecture
  • Docker, Kubernetes for containerization and deployment
  • Testcontainers for integration testing, JUnit for unit testing

Frontend (when full stack is needed):

  • Angular, React/Next.js, Thymeleaf
  • Responsive, production-grade UI integration with backend APIs

What sets my work apart:

  • Real banking-domain experience: transaction systems, KYC flows (AWS Rekognition), audit logging, real-time monitoring
  • Clean, maintainable code not just "it works," but code your next developer can read
  • CI/CD experience (Jenkins) so your deployment isn't an afterthought

Whether you need a single API endpoint or a complete backend architecture, I'll scope it clearly upfront so there are no surprises mid-project.
